Description
Technical field
Steel drum manufacturing technology field is the utility model is related to, specifically a kind of stand special bolt.
Background technology
Steel drum is important transportation package holdses, with industrial expansion, in the pail pack class that chemical industry, food service industry use
In, open steel drum, opening necked-in drum, opening cone tank etc., which are obtained for, to be widely applied.This kind of steel drum have one it is common
Feature, they are all stands, and bucket top is bung, and the fixed form of its bung uses closing ring formula sealer.Closing ring
Formula sealer is divided into two kinds of screw type sealer and level type sealer again, wherein screw type sealer because it is simple in construction plus
Work is easy, manufacturing cost is low, solid and reliable during use and be widely used.But needed because it uses standard bolt, during installation
Want two spanners, operation extremely inconvenience.
Utility model content
The purpose of this utility model is：For existing screw type sealer, it is proposed that a kind of stand special bolt,
Bolt head carries locking plate, and locking plate is stuck in the lock ear of closing ring, limits freely rotating for bolt, only needs one during installation
Spanner, operation is extremely convenient, greatly increases the packaging efficiency of steel drum.
Technical scheme is used by the utility model：A kind of stand special bolt, including screw rod, bolt head and spiral shell
Mother, the bolt head both sides are provided with symmetrical two sections；The bolt head is provided with locking plate, and the locking plate can be stuck in
In the lock ear of closing ring, freely rotating for bolt is limited；The nut, which tightens screw rod, can be stuck in another lock ear of closing ring
On, limit moving freely for bolt.
In addition, the utility model also provides following attached technical scheme：
Preferably, the cross section of the locking plate and bolt head is into " L " shape structure.Locking plate is set to be stuck in envelope more securely
Close in the lock ear of hoop, only need a spanner during installation, operation is extremely convenient
Preferably, the stop length of a film 2-5cm.Locking plate moderate length, it is easy to be stuck in the lock ear of closing ring.
Preferably, camber above and below the bolt head.Spanner is set to be easier to block bolt head.
Preferably, the bolt head and locking plate are integrated.Make structure more solid and reliable.
Preferably, the width of the locking plate is less than the width of bolt head.It is easy to block bolt head with spanner, limits spiral shell
Bolt freely rotates.
In use, locking plate can be stuck in the lock ear of closing ring, freely rotating for bolt is limited, nut tightens screw rod can
To be stuck in another lock ear of closing ring, moving freely for bolt is limited, tightens the special bolt head of stand special bolt
Portion is provided with symmetrical two sections, and spanner can be used when wherein any one is damaged for bolt, locking plate, nut or lock ear
Bolt head is blocked, limits freely rotating for bolt, there is plain bolt to have basic function.
The utility model has following beneficial effect：
1st, a spanner is only needed when the utility model installs screw type sealer, operation is extremely convenient, greatly carries
High steel drum packaging efficiency.
2nd, the utility model can use spanner when wherein any one is damaged for bolt, locking plate, nut or lock ear
Bolt head is blocked, limits freely rotating for bolt, there is plain bolt to have basic function.
3rd, the utility model is scientific and reasonable for structure, simple and practical, is easy to promote the use of.
